RAID controller temperature
The operating temperature in the card specs say: 0°C to 55°C
However, when I check its status, it gives me this: 85 C/ 185 F (Normal)
So the question is why is it saying Normal when the temperature is over the operating temperature specs of 55 C? Concerning or that is really normal?
Controller status says Optimal.
Comments
The temp is measured 1" away from the heatsink. For normal operation the raid cards needs around 80°C. It is similar to a car engine that needs optimal temperature to reach the best performance.
That is why the transfer speeds are slower until the raid card heats up.
That's the ambient temperature. Integrated circuits will have an operating spec in addition to much higher temperatures on the die and junctions of the chip.
Tl;dr 0-55*C refers to the room temperature, not the chip temperature.
Thanks! I found the maximum operating die temperature: 100°C, so it should be fine even though I'd have preferred it to be lower but I guess they have to balance additional cooling costs.

Haha.
Less than 1c
85°C won't be a problem since it is so close to the chipset. Anywhere below 110°C should be fine.
